摘要：In the present study, two widely adapted common Indian plant species viz. Dalbergia sissoo and Nerium oleander were examined for normalized isoprene emission rate (NIER) using dynamic flow through bag enclosure technique. An attempt has also been made to evaluate suitability of these two selected plant species for city plantation programmes. Dalbergia sp. has got high isoprene emission (84.67 ± 3.87 μg/g/h) while Nerium sp. has minimum (0.001± 0.17 μg/g/h) during summer season as compared to monsoon season. Thus, Nerium oleander falls under low isoprene emitting category while Dalbergia sissoo, under high isoprene emitting category. The plants having low emitting isoprene rate due to non-functionalization of this lightdependent Isoprene-synthase (IspS). Hence, Nerium oleander should be encouraged for further city plantation at roadsides and Dalbergia sissoo should be done on low scale expecting reduction of other harmful pollutants in air.
